Document Type and Number:
Japanese Patent JP2021071803
Kind Code:
A
Abstract:
To appropriately reproduce behavior of a particle model in an analysis model, in composite material analyses by a computer using a molecular dynamics method.SOLUTION: An analysis method causes a prediction module to perform machine learning using learning data that includes at least information on positions of a particle model for learning that models substances in a composite material before and after a lapse of a predetermined time by calculating behavior by a molecular dynamics method using a learning model including the particle model for learning. This prediction module obtains information on a position of a particle-of-interest model by predicting the information on the position of the particle-of-interest model after the lapse of the predetermined time using information on a relative position of a neighboring particle model around the particle-of-interest model relative to the particle-of-interest model, with a particle model for an analysis in a composite material analysis model as the particle-of-interest model. In the prediction by the prediction module, prediction modules are prepared separately for a particle model for a first analysis and a particle model for a second analysis, which model first and second substances in the composite material.SELECTED DRAWING: Figure 1A
